METHOD AND SYSTEM FOR CODING HUMAN SPEECH FOR SUBSEQUENT REPRODUCTION THEREOF |
摘要 |
Human speech is coded for subsequent reproduction through the following steps: (a) receiving an amount of human-speech-expressive information; (b) estimating all complex poles of a transfer function of an LPC speech synthesis filter that has a spectral envelope corresponding to the information; (c) singling out from the transfer function all poles that are unrelated to any particular resonance of a human vocal tract model, while maintaining all other poles; (d) defining a glottal pulse related sequence representing the singled out poles; (e) defining a second filter with a complex transfer function to express all the other poles; (f) outputting speech represented by a filter based on combining the glottal pulse related sequence and a representation of the second filter. |
